Debt erection

I said you'll wear that outfit to work or I'll put you over my knee!
How dare you question me. Do you know how much it cost to find a matching bustier, knickers and stockings in hot pink and black in your size? Leopardskin pink and white stockings don't grow on trees, you know.
But I will let you work off your debt between my legs, For every hour you spend kneeling in front of me tonguing my clitoris, I'll knock a pound off your bill.
Yes, it will take quite a while. And while any money is still outstanding, you'll be wearing your sexy little outfits. And you will be my oral slave.
